where \(G_{ij}\)  is the Green's function that captures the displacement in the elastic medium at the location of one cell (dipole) caused by the application of a point force at the location of the other [1]} defined as
\(G_{ij}({\bf r}) = \frac{1+\nu }{\pi E} \bigg [(1-\nu ) \frac{\delta _{ij}}{r} + \nu \frac{r_i r_j}{r^3} \bigg ].\)
